I normally wouldn't ever suggest a cheap car cover. They are tough on paint , especially if they are in a windy area and left on for a long period of time. But since you said the paint could already use some correction and you'd only use it occasionally, then I wouldn't worry about it too much. Any small scratches it would cause in the paint can probably be taken care of with a good detailing. But cheap covers left on outdoors for long periods of time can be brutal on paint
